Which country has the highest per capita income?

• A. Luxembourg
• B. Norway
• C. Qatar
• D. Singapore

Answer: (C)

Per capita income is the average income earned by each person in a country, calculated by dividing the total income (usually GDP or GNI) by the population. It shows how wealthy the average person would be if the country’s income were shared evenly, but it doesn’t reflect how wealth is distributed or the overall size of the economy.

A country with enormous wealth from natural resources and a relatively small population can have an exceptionally high per-person income, because the vast earnings are spread across fewer people. This is the situation that makes the chosen country stand out: its deep energy revenues combined with a small, manageable population push the average income per person to very high levels.

The other countries on the list also have high per-capita income for different reasons—Luxembourg through a strong finance sector and high wages, Singapore through a highly developed, diversified economy, and Norway through substantial oil wealth—so rankings can vary by year and by whether the measure uses nominal GDP per capita, GNI per capita, or PPP. The key idea is that per-person income reflects average wealth and is influenced most by resource wealth, industry structure, and population size.
